What I`ve wondered,if they have done any *non-mainstream* weights,0W40,5W40,10W40,15W40,20W50,etc? I`d like to see side by side add pack comparisons of say for example,PYB 5W30 vs their 10W40,20W50 to see if there`s anymore additives in the non starburst oils.

PQIA is mainly interested in the lowest tier of the oil market. They aren't testing how good oils are. They are testing how bad some oils are, especially for people who know nothing and just grab a jug off the shelf of the convenience store. While PQIA's quantitative analysis of the good oils might be somewhat interesting to a few of us, their analysis of the real junk-in-a-bottle is important to help get the bottled trash off the shelves.
